Has anyone tried to profile papers on a 9900/7900 using Snow Leopard? All of my profiles, so far, have been generated with Leopard (10.5.X) using the work flow of having an untagged target and assigning Generic RGB as the profile and telling the driver to let the printer manage color with the printer driver set to 'No color management'. Doing this under SL generates a print that is obviously different then the print generated under Leopard.
There are two workflows you could try assuming Photoshop CS4, MacOSX 10.6 and the latest Epson version 6.55 driver:
Workflow 1.
Use your existing workflow but instead of assigning Generic RGB, assign sRGB.
Workflow 2.
- Open the Colorsync Utility, click on the Devices tab and expand the entry for your 7900/9900.
- The default "Mode" profile should be sRGB if you are using the version 6.55 Epson driver.
- Change the "Current Profile" from sRGB to the profile for the media type you will be using to print the chart.
- Open the chart with CS4 but do not assign a profile.
- Choose "No Color Management" in the Photoshop dialogue.
- Choose "Color Settings: Off" in the print driver dialogue.
- Make sure that the correct media type is chosen so as to match the changes made in CU.
I have tried both methods and they seem to be identical to many previous tests I have tried and documented below.
